Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full behavioral burden, yet it only discloses the acting role ('Team owner'). It says nothing about whether this consumes a paid/billable seat, what happens on a duplicate invite, idempotency, whether an invitation email is sent, or error conditions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with the role, action, and target in order, and no filler. It is arguably over-terse for a mutation that likely has billing side effects, but nothing in it is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutation tool with no annotations, no output schema, and no stated side effects, one sentence is not enough for an agent to invoke it confidently. The parameter surface is covered by the schema, but the consequences of calling it are not described anywhere.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both parameters are already documented in the schema, establishing a baseline of 3. The phrase 'for a member email' loosely ties to member_email, but the description adds no meaning for org_id and no format or constraint detail beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb and resource ('provisions a seat license') plus the scoping target ('for a member email'), which is clearly actionable. It does not name or contrast with the obvious inverse sibling, revoke_team_seat, so an agent must infer the distinction from the names alone.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied rather than stated: the 'Team owner:' prefix signals the required role, and 'for a member email' implies the invite/provisioning scenario. There is no explicit when-to-use guidance, no exclusions, and no pointer to revoke_team_seat or get_license_status as related operations.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
